Double top and double bottom

What completes a double top?

• The second peak reaching the first peak's level
• Any wick below the trough
• A close below the trough between the peaks

A double top completes and later a daily close lands back above the neckline. What is that close?

• The kill close: the completed pattern no longer stands
• A retest that confirms the pattern
• Irrelevant once the pattern has completed
